METHOD OF TREATING THE TIPP ING MATERIAL 0F CIGARETTE-TUBES.

Specification of Letters Patent. Application filed June 15, 1912. SerialNo. 703.872.

Patent ed May 13,1913.

To all whom it may concern Be it known that I, Ewan) Konaxnn. a subjectof the Emperor of Germany, residing at Dresden, Germany havc invented anew and useful Method of Treating the Tipping Material ofCigarette-'luhes, of which the following is a specification.

In the manufacture" of cigarette tubes which are tipped with some stitl'mouthpiece material such as cork or the .like it is difiicult to obtaina smooth and continuous joint betweenthe tipping material and the restof the tube oiving to the difference in the rigidity of the twomaterials.

The present invention relates to a new step in the art of applyingmouth-piece ma: terial to cigarettes or cigarettfe tubes with a view toovercoming the ditiiculty above mentioned and consists in first passingthe tipping material, either separately or in combination with thecigarette paper, previous to the formation of the tube, through a diewhich sets the edgesthereof to substantially the shape they are goin itohave on the completed tube, and then atiixing the shaped and set tippingmaterial to the end of the-cigarette. Treated in this manner'the tippingmaterial will lose its tendency to straighten out and will form a smoothcontinuous joint with the cigarette paper.

The die through which the materials are passed may be of variousconstructions and may either be used .cold or'adapted for heating.Several forms of such dies are illustrated by way of example in theaccompanying drawings, Figure 1 representing an end view of one form ofdie. Fig. 2, a longitudinal section of the same, and of the materialunder treatment, means being. shown for heatiug'thc die, Fig. 3. a viewof a die composed oi grooved rollers between which the strip is passedtogether with the shaping block. Fig. 4;. a side view of another form'ofdie. Fig. 5 an end view of the same, Fig. (i, a side view of yet anotherform, and Fig. 7, an end view of the latter.

in Figs. 1. 2, and 4- to 7 the die is desig natcd l and the tippingmaterial, which may consist of cork or the like, is designated 2. Thetipping material is drawn through the die, as indicated in the figures,the die be- Copies of this p tent may be obtained for five cents each,

ing formed so as to impart to the cork strip, or at least to the marginsthereof. the shape or substantially the shape they are going to have onthe completed cigarette tube. The strip as thus shaped and set is thenapplied to the month end of the cigarette or cigarette tube in thc'usualway. as for instance by hand or by suitable mechanism. and inasmuch asthe mouth piece material has been shapedand set before its applicationto the cigarette. a smooth and continuous joint will result. The diesmay be heated in any suitable manner. for instance by flames arranged asshown in Fig. 2.

' The die shown in Figs. 4 and 5 is adapted to shape the tipping stripso as to fit flatpressed cigarettes. in Figs. 6 and T a die is shownwhich bends the whole strip into a tube. with overlapping ends.

According to Fig. 3 a shaping block 3 is provided which is passedtogether with the strip between three grooved rollers i set at an angleto each other. The rollers shape the strip by pressing it against theblock.

()ther arrangements may bc'rcsortcd to as long as the stitl tippingmaterial is bent to shape before the cigarette tube formed and beforethe tipping material is afiixed thereto.

I claim 1. The method of applying mouth-piece material to cigaretteswhich consists in bonding and setting a strip of mouth pi'ece materialto a shape cm'rcsponding substantially to the form of the cigarette towhich said mouthpiece is to be applied and then permanently attachingthe mouth-piece to an end of the cigarette.

2. The method of applying mouth-piece material to cigarettes, whichconsists in sulr jecting a piece of the said material to the.simultaneous action of pressure and heat be tween dies shaped to bendand set said material to substantially the. form of the cigarette towhich the material is to be applied and then ailixing the said shapedmouthpiece to an end of the cigarette.
